Tackfest Tuesday- Whyyyyyyy do you build me up?

I'm in remarkably chipper form today. It's something to do with booking a weekend away with Mr. Allan and relaxing after the boy's third birthday.
My creative juices are flowing with Signed, Sealed, Delivered and tonight I will hit the 50,000 word mark. So all in all, it's a good day.
So today's tacky song reflects that mood. Even though it is actually quite a sad sony lyrically, it always makes me grin like a buck eejit. It reminds me most of all my aunt's 50th birthday party and my own 30th...
So everybody, I give you 'Why Do You Build Me Up?'

Why do you build me up (build me up) Buttercup, baby
Just to let me down (let me down) and mess me around
And then worst of all (worst of all) you never call, baby
When you say you will (say you will)
but I love you still
I need you (I need you)
more than anyone, darlin'
You know that I have from the start
So build me up (build me up) Buttercup,
don't break my heart"
